Field emission in vacuum microelectronics
WebThis book is dedicated to field emission electronics, a promising field at the interface between "classic" vacuum electronics and nanotechnology. In addition to theoretical models, it includes detailed descriptions of experimental and research tec... As already indicated, the early experimental work on field electron emission (1910–1920) was driven by Lilienfeld's desire to develop miniaturized X-ray tubes for medical applications. However, it was too early for this technology to succeed. After Fowler–Nordheim theoretical work in 1928, a major advance came with t…
